Columbus’s Matt Calvert celebrates his game-winning goal with teammates Ryan Murray (27) and Cam Atkinson during the second overtime period of Saturday’s NHL playoff game in Pittsburg. The Blue Jackets won 4-3 to even the series at 1-1.

PITTSBURGH — Matt Calvert banged home a rebound 1:10 into the second overtime and the Columbus Blue Jackets earned the first playoff victory in franchise history with a 4-3 win over the Pittsburgh Penguins on Saturday night.

Pittsburgh’s Marc-Andre Fleury stuffed the initial shot by Cam Atkinson but Calvert stood all alone at the left post and wristed a shot into the open net to even the Eastern Conference quarterfinals at one game each. Game 3 is Monday in Columbus.

Jack Johnson tied the game with 6:01 left in regulation for the Blue Jackets. Ryan Johansen also scored the first playoff goal of his career for Columbus. Sergei Bobrovsky overcame a shaky start to finish with 39 saves.

Brian Gibbons scored twice and Matt Niskanen added his second goal of the playoffs but Pittsburgh was outplayed for much of the final three-plus periods. Fleury made 41 stops but was helpless on the game-winner.

BLUES 4,

BLACKHAWKS 3, OT

ST. LOUIS — Defenseman Barret Jackman scored on a drive through traffic, giving the Blues their second straight 4-3 overtime victory over the Blackhawks for a 2-0 series lead against the defending Stanley Cup champions.

St. Louis rallied after Chicago defenseman Brent Seabrook received a five-minute major and game misconduct penalty for a vicious elbow to the head on Blues captain David Backes, who had to be helped off the ice, went straight to the locker room and did not return for the extra period.

Vladimir Tarasenko forced overtime with his second goal of the series, beating Corey Crawford with a wrist shot that banged off the right post and in with 6.4 seconds to go. Kevin Shattenkirk had a goal and two assists for the Blues.

Duncan Keith, Seabrook and Michael Rozsival scored in a span of five shots to put the Blackhawks up 3-2 early in the third. But Seabrook’s penalty proved costly, and he could be suspended for Game 3 in Chicago on Monday night.

The Wild were unable to contain the quickness of teenager Nathan MacKinnon, who had a goal and three assists. Stastny, the star of Game 1, also had a goal and three assists.

His empty-netter sealed the victory after Marco Scandella made it a one-goal game with 1:19 remaining.

Charlie Coyle also scored early for the Wild.

Game 3 is Monday in Minnesota.

Landeskog’s second goal of the game gave Colorado a 3-1 lead with 8:01 remaining in the second and led the Wild to pull erratic starter Ilya Bryzgalov. Backup Darcy Kuemper stopped all 14 shots he faced, possibly opening up a goaltender controversy.
